The success behind both the brands can be attributed to the similarities in their existing activities of the value chain with that of the new market. [Cavanaugh, 2009] “The prominent focus upon operational and control activities of an organization compared to its planning and marketing counterparts has resulted in emergence of sophisticated systems for the purpose of gathering, processing and distributing the internally generated information such as costs, inventories, and personal data; while relatively unsophisticated systems suffice for coping with crucial externally generated environmental information system.

INFORMATION SYSTEM MODEL “An information system uses the resources of people, hardware, software, data, and networks to perform input, processing, output storage, and control activities that convert data resources into information products.

Data are first collected and converted to a form that is suitable for processing (input). Then the data are manipulated and converted into information (processing), stored for future use (storage), or communicated to their ultimate user (output) according to correct processing procedures (control)” [Sachenko, 2010] Information system involves a stream of strategic, managerial and operational activities which includes ‘processing, storing, distributing and using’ the collected data along with the technological information.

Another application of information system involves “creating interorganizational information systems to create or sustain competitive advantage include establishing consortia- electronic exchanges for suppliers and buyers. ” [Scribd, 2010] Out of the various information systems available, information technology is the most pivotal one.

Other examples of IT integration in the company involve the “wireless devices, intelligent scales, electronic shelf labeling, self check-out machines and radio-frequency identification systems. RFIS) Altogether the information systems model tends to provide a market-oriented and pioneering contribution to Tesco such that there evolves an augmentation in product/service volume while controlling costs as well. [Ivory research, 2010] So for effective functioning of organization activities and in achieving organization objectives of expanding the company, it is essential that the organization follows an outright plan such that it can achieve its goals. .
